Also carried out to support passing quality assurance tests for US and China markets.Due to the structure vulnerable to eco-performance, such as a decrease in the resonance point of the voice signal and an amplification of the echo due to the arrangement and foldable structure of two RCVs and SPKs, to adjust the mechanical structure and gain redistribution were guided. As a result, it was able to contribute to the previous launch as well as pass the field test.
